Which is not a step used when constructing a perpendicular from a point not on a given line?
a. without changing the compass, from each intersecting arc on the line, construct two arcs on the side opposite the given point.
b. draw a line from the point to the intersecting arcs.
c. from the point not on the line stretch the compass and mark two arcs on the line.
d. use your ruler and draw a straight line from the point through the line

Answer with explanation:

Given a Point and a Line

Step 1

D.  Use your ruler and draw a straight line from the point through the line.

Step 2

C.From the point not on the line stretch the compass and mark two arcs on the line.

Step 3

A. Without changing the compass, from each intersecting arc on the line, construct two arcs on the side opposite the given point.

→→Not a Step

B. Draw a line from the point to the intersecting arcs.

The correct step will be

Mark arc from both the arcs.The point where these two arcs intersect is the point from which the perpendicular line will pass.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
